A spring 29 extends over the hood which is simple and rugged in construction, thorguide 21 and has its ends attached to the cylinl0 ougly reliable in use, easy to manipulate, conder. This hood guide is pivotally mounted on 10 venient, and otherwise well adapted for the purthe pin 20. I pose to which it is designed. The operation of this device is as follows: The
